The natural female steroid hormone with the greatest estrogenic activity is 17ß-estradiol. It is important to note that some synthetic estrogens, such as diethylstilbestrol (DES), moxestrol, and 11b-chloromethyl estradiol show 10 times more estrogenic activity than 17b-estradiol in the E-SCREEN assay [136]. Ethinylestradiol has the same estrogenic activity as 17b-estradiol, whereas the activity of the synthetic EDCs is by some orders of magnitude lower [136]. In this context it is important to note that most, if not all, efflu- Bioaccumulation and Occurrence of Endocrine-Disrupting Chemicals (EDCs) 37 ents of sewage treatment plants [145 b] and some rivers [145 c] in the United Kingdom are estrogenic to fish.
